Go to Bed, Save Calories

Need a good reason to call it a night? Here you go: A recent study from Northwestern University found that those who stayed up really late and slept in (3:45 – 10:45 am) consumed an average of 248 more calories daily than those who hit the sack and rose earlier (12:30 – 8:00 am). These extra calories could add up to an additional two pounds per month!Researchers also found that the late nighters had a higher body mass index than "normal" sleepers, a diet that included twice as much fast food, more sodas and only half as many fruits and vegetables. Not surprisingly, the extra calories were usually consumed at dinner and later in the evening.
